"Rui balances these forces: develop a desktop application in JavaSwt or Perl Rui, and deploy to the web using Rui. Developers develop using a rich UserInterfaceFrameWork such as SWT or Perl Rui , and deploy to WebBrowsers with no ActiveX, plugins, or Java on the client.

"Users get a rich and thin UI, with minimal loss of fidelity. Developers are freed from working with DHTML, JavaScript, and clunky web application frameworks."
